Re: ArrayList nullIfEmpty
(Presumably the title was meant to be ArrayUtils nullIfEmpty :) )
Best way is to open a JIRA issue up
(http://issues.apache.org/jira/browse/LANG).
The below should be defaultIfEmpty rather than nullIfEmpty I suspect
to match StringUtils/ObjectUtils.

Yes, thanks for reading my mind. In the body, I also said ObjectUtils
where I meant ArrayUtils :(. So many different Utils I got myself
twisted around.

I'll open the Jira issue.

I thought about that, but there doesn't appear to be any reasonable
default for arrays other than null. I don't object to default though,
as for my purposes I can simply pass null for the default.
